Title: Means for actuating ejectors and cores in moulding machines
IPC: B22D17/22
Filed: 1948-02-29
Abstract: 654,183. Injection- and compression-moulding machines. A.R.D. CORPORATION. Feb. 29, 1948, No. 6358. Convention date, Jan. 30, 1947. [Class 87 (ii)] [Also in Group XXII] An injection- or compression - moulding machine has hydraulic means for removing cores from and ejecting a moulded article. An injection - moulding machine comprises a fixed mould part 16 and a mould part 20 which is moved towards and held against the part 16 by hydraulic apparatus 32 acting through a movable platen 14. Ejector pins 36, carried by a plate 34 secured to a hollow piston-rod' 38, are raised and lowered by supplying fluid through a pipe 116, a four-way valve 114 and either of pipes 110, 112 to a cylinder 42 which actuates the piston-rod 38. Cores 68 are raised and lowered by supplying fluid through a four-way valve to a cylinder 60 to actuate a piston-rod 64 which is attached to a core-plate 66. The core-plate 66 may be attached to the rod 38, and the ejector-plate 34 to the rod 64. The ejection and core withdrawal may be carried out during the movement of the platen 14 or when it has been lowered and is stationary. The mould parts may move relatively to each other in a horizontal or a vertical direction. The Specification as open to inspection under Sect. 91 comprises also a moulding-machine for moulding articles which do not require cores. In such a machine either the core-plate 66 is removed and the ejector-plate is mounted on both piston-rods or the core-plate and its piston and actuating-mechanism may be omitted. It also comprises a moulding-machine in which the usual hydraulic press operating means co-operates with the top platen. This subjectmatter does not appear in the Specification as accepted.

IPC: H03F1/54
Filed: 1950-03-14
Abstract: 670,404. Automatic frequency control systems. STANDARD TELEPHONES & CABLES, Ltd. March 14, 1950, No. 6361/50. Class 38 (iv). [Also in Group XL (c)] A frequency modulation radio repeater of the type described in Specification 663,803 is provided with fault alarm arrangements (see Group XL (c)). Fig. 2 shows a frequency discriminator for supplying the control voltage to the frequency controlling motors and to the alarm arrangements comprising rectifiers 55 and 56, and a transformer 39 whose secondary is divided into two equal parts, the centre point being connected to one terminal of the primary. The transformer is tuned to the intermediate or difference frequency by capacitors 40, 41, and is preceded by an amplifier comprising valves 42, 43, 44, the input being applied at terminals 47, 48. To simplify the control of the motor the input to the discriminator is chopped at, for example, 50 c.p.s. by applying a rectangular wave of this frequency to the terminal 49 so that the valves 42 and 43 are cut off for alternate periods of 0.01 seconds duration. Filters 57, 58 remove the intermediate frequency from the output. The limiter circuit comprises rectifiers 61, 62 biased from a negative source connected at' 63. Negative voltages interrupted at 50 c.p.s. are available at terminals 20, 22 and are equal when the, intermediate or difference frequency has the correct value.

Abstract: 584,440. Control of motors. BRITISH THOMSON-HOUSTON CO., Ltd., LIDDIARD, H. W. C., and PETCH, T. H. April 6, 1944, No. 6430. [Class 38 (iii)] [Also in Group XXXV] A synchronous motor SM driving a Ward- Leonard generator G, or other variable-load generator, is provided with an exciter ME having a constantly-excited field winding MEFI and a field winding MEF2 excited from a variable-voltage exciter VVE, and a rectifier R, which may be a bridge-connected rectifier, is provided in the connection between the exciter VVE and the field winding MEF2. The exciter VVE may be driven by the motor M of the Ward-Leonard set, and the field VVEF fed from a shunt in the main generator armature circuit so that the exciter produces a voltage substantially proportional to the power output of the main generator. In order to prevent regeneration the rectifier R passes current only in the sense that the field MEF2 strengthens the effect of the field MEF1. With a bridge-connected rectifier the cumulative effect of the two fields is preserved when the main current reverses.

Title: Multi-channel pulse communication systems
IPC: H04B14/02
Filed: 1956-03-02
Abstract: 794,776. Multiplex pulse signalling; non- linear amplifier circuits. STANDARD TELEPHONES & CABLES, Ltd. March 2, 1956 [March 9, 1955], No. 6603/56. Classes 40 (5) and 40 (6). A multi-channel pulse time modulated communication system employs interlaced pulses and a single compressor and expander forming a compandor system, in which the compressor is a delay device controlled by a waveform which is derived from the channel gating pulses by integration, shaping and delay and subsequent distortion. The delay device forming the compressor-expander circuit, Fig. 3, comprises a monostable multivibrator with valves 24 and 25, stable when valve 24 conducts and valve 25 does not, diode 29 defining the grid bias on valve 24. Diode 31 permits negative pulses only to trigger the circuit. A negative pulse being applied, valve 24 ceases to conduct, valve 25 conducts, a negative pulse appearing at its anode, which is differentiated by condenser 35 and resistor 36, and applied to the grid of valve 24, this circuit also determining the time at which the multivibrator returns to its stable state. Since the duration of the output pulse from valves 24 and 25 is a linear function of the voltage applied to the grid of valve 25, then by applying a special waveform thereto the circuit operates as a compressor, or expander. The special waveform generator, Fig. 6, is synchronized by gate pulses from the distributor, integrated and shaped and applied to a delay circuit, to form a sawtooth input. This input is applied to the cathode follower 70 and thence to amplifier stage 74, the anode of which is connected to the output terminal 76 and to a non-linear feedback path comprising diodes 77, conductor 78, cathode follower 79 and feedback resistor 80. The feedback circuit together with amplifier 74 produces a segmented approximation of the compressor or expander characteristic circuit. When quiescent diodes 77 are non-conducting, feedback is maximum, and valve 74 at minimum gain. The diodes are maintained at a threshold condition by the B supply and voltage divider 81, which is so arranged that diodes 84, 83 and 82 successively conduct when the sawtooth voltage reaches certain given positive potentials above a reference voltage, and diodes 85, 86 and 87 conduct when it reaches a given negative voltage. Switch 88 selects either one positive and one negative conducting diode or three of each, according to the characteristic desired. As the degree of feedback varies in accordance with the clipping action of the diodes the output waveform closely approximates the desired compression or expansion characteristic. In a second embodiment of the system, Fig. 7 (not shown), individual compressors and expanders are used for each group in a group multiplex system.

In a modification, Fig. 5, a single-piece axle A is used, mounted in a housing B and carrying a rack bar C engaged by a worm wheel D operated by a worm E connected to a hand-wheel as before. In this example, the wheels A<1> are moved together transversely to the frame. The mechanism is self locking and provides a mechanical advantage in operating the axle. In both examples, the housing B is pivotally mounted at B<3> on a frame member so that the angular position of the axle can be varied. The operating means comprise a rod G and handwheel worm gearing G' for rotating the horizontal spindle C<2> of a pulley H around which pass chains H' connected to clips on the ends of the axle housing.
